Hi Alex,

Good question. This is what the config.h file is for. It's installed
into $prefix/include/gnuradio/config.h. If ControlPort is defined and
built for the project, it will be defined in this file as "#define
GR_CTRLPORT". If you include that header file, you can test #ifdef
GR_CTRLPORT in your own work.
